Phys. Rev. Lett. 68, 2409–2412 (1992)Scalar Aharonov-Bohm experiment with neutronsSee Also: Erratum Received 3 January 1992; published in the issue dated 20 April 1992 The scalar version of the Aharonov-Bohm effect predicts a phase shift for de Broglie waves due to the action of a scalar potential in an otherwise field-free (i.e., force-free) region of space. Unlike the more familiar effect due to the magnetic vector potential, the scalar effect has hitherto remained unverified due, presumably, to technical difficulties in electron interferometry. Rather than using electrons acted on by electrostatic potentials, we have performed an analogous interferometry experiment with thermal neutorns subject to pulsed magnetic fields. The expected phase shifts have been observed to a high degree of accuracy. © 1992 The American Physical Society URL:
